A gimbal having a base portion and a tongue joined together by a neck portion. The base portion includes a first proximal edge facing away from the tongue. A circuit is mounted on the gimbal and includes a portion mounted to the base portion having a circuit extension region that extends beyond the first proximal edge. The circuit extension region includes a second proximal edge facing away from the tongue. A slider may be mounted on the tongue and electrically connected to the circuit. First and second PZT actuators are mounted to the head gimbal assembly and electrically connected to the circuit. The circuit extension region has a circuit extension region width W of at least 0.1 mm as measured in a direction extending away from the tongue relative to a furthest extending portion of the first proximal edge and a furthest extending portion of the second proximal edge.
